The JVC GW-SP100 is a 4KCAM remote camera head and recording unit; the system includes the camera head, a recording/playback device with built-in monitor and a RCU controller. This tiny camera records at HD and 4K Ultra HD, at 4:2:2 150Mbps, and supports up to 50/60p recording in both HD and 4K. 4K footage is recorded as a single file in AVC H.264 format at 150Mbps. Thanks to the system's two dual codecs and four card slots (two for 4K, two for HD), the camera can record 4K+4K and HD+HD (continuous/back-up recording), making it a very flexible system. Recording is via cost-effective SDHC/SDXC cards; a single 64GB UHS-I U3 SDXC card provides around an hour of recorded 4K footage at 60p.

I have scoured the internet, tried everything I could find about the JVC GW-SP100 4K video to iMovie/FCE and iPhoto workflow. The final result I found from all relevant forums is that iMovie/FCE/iPhoto doesn't do 4K videos. To solve these problems effectively, it will be better to transcode JVC SP100 4K H.264 video format to a more "edit" friendly codec. Different from 720p/1080p videos, the conversion of 4K video is in a higher standard, a professional 4K Video Converter is what you need.
